28272.79.WH3: Ajax DoubleButton: A Reliable Wireless Emergency Solution
The Ajax DoubleButton is a sophisticated wireless emergency button designed to prevent accidental presses while ensuring a reliable alarm system. Its design and features cater to both private and commercial properties, meeting professional European security standards.
Accidental Press Prevention
One of the standout features of the Ajax DoubleButton is its design to prevent false alarms. The device requires simultaneous pressing of two buttons to activate the alarm. These buttons are intentionally stiff and separated by a plastic barrier, ensuring that accidental presses are virtually impossible when carrying the DoubleButton in a pocket or bag.
Confirmed Alarms
To prevent unnecessary dispatches, the DoubleButton supports a system of confirmed alarms. This feature involves instructing users on the specific sequence of presses required to generate a confirmed alarm condition. Such a system provides a 100% guarantee that a hold-up alarm was raised intentionally and only by an authorized user.
Confirmation Options
-
Single DoubleButton Confirmation: Users can confirm an alarm with a single DoubleButton by following the designated sequence.
-
Two DoubleButtons Confirmation: For added security, using two DoubleButtons can further ensure that alarms are intentional.
Guaranteed Alarm Delivery
The hold-up device uses the Jeweller, a two-way radio protocol, to transmit signals to the hub over a range of up to 1300 meters. The successful delivery of a DoubleButton alarm is verified by a flashing LED. Jeweller encrypts the transmitted data to prevent forgery and interference. If the system detects interference, it automatically switches to a free radio frequency and notifies users and the security company of the situation.
PRO-Technology for Versatile Use
Ajax DoubleButton is designed to be a PRO-technology solution, suitable for various environments. Its wireless connectivity with the hub and long communication range allow users the freedom to place and carry the DoubleButton as needed. This flexibility makes it an ideal choice for securing both private and commercial properties.
In summary, the Ajax DoubleButton is a reliable and advanced emergency button solution that combines security, ease of use, and versatility, ensuring peace of mind for its users.
